Administration Guide : Xinet Logging : Preview Generation logs

Preview Generation logs
The Logging, Preview Generation subtab allows you to open various pages that provide more information about the server as it builds previews. The Pending page, shown in , displays a summary of requests that have been made to the fpod(1M) daemon which are to be passed on to programs such as mkfpo, pdfsync and mview, among others.
The actual “log” files can be examined using FPO/WEB History and Syncing History pages or can also be found in these locations on the server:
Unix /var/adm/appletalk/fpo_log
Windows C:\Program Files\Xinet\FullPress\Admin\fpo_log.wri
C:\Program Files\Xinet\FullPress\Admin\fpodq\vlog.wri
The page summarizes information about requests currently being processed, those that are waiting to be processed and instances where a process is on hold. Waiting means that it’s time to process that entry, but the server has to wait for some other process to finish first. (Xinet only allows one item for the database to be processed at a time and allows only some small number of previews to be processed by mkfpo(1) at once). Holding means that there’s an explicit time delay on the entry, and after whatever amount of time elapses, it will move to Waiting.  Jobs sent to mkfpo(1) that have failed go into the Holding queue.
Depending on the modules you have licensed, you’ll find information about:
The page provides shortcuts to the Details page where you can find more information about the files in the request queues and their individual delay times. The Pending page allows you to quickly remove (in a batch) any unprocessed requests in a queue, except for FPO/WEB Previews. You may remove FPO/WEB Preview requests individually using the Details page. (Should you want to build previews at a later time, follow instructions in Using the fpod.conf file for advanced administration.)
If you find requests are being held, use the Details link to find out how long. It might also then be necessary to look at the FPO/WEB History log file once you’ve identified the file in question, to determine the best course of action.
To find out more information about files waiting in various preview queues, use the Logging, Preview Generation, Details page. After selecting the Details tab, use the Select Queue popup list to identify the queue you want to examine. .
You’ll find the file name(s) for any delayed files, information about how many attempts have been made to process the file, and how long the delay will be until the server tries again. (As shown above, the server keeps trying to process problematic files, at growing intervals.) The Details page also makes it possible to delete individual files from being processed, unlike the option seen on the Pending page, which deletes all waiting files in a queue.
Once you’ve identified a problem file by name, you may find it helpful to scan the fpo_log, found on the FPO/WEB History page for more information about it.
